Milk Bottle

My baby girl prefer direct latch. She dislike to use milk bottle. How do you swift to milk bottle? I tried Avent, pigeon teat. Both she dislike. Previously she is using Medela and pigeon. But now she totally don't want to use milk bottle. Seek advise from mummies. She is 2.5 months old. But I give her 4m+ teat. Or should I buy bigger size for her?
